Didn't even need to shove 42 Gjallarhorns down his throat to beat him yesterday. We just stun locked him with 2 Blackhammers and an Eye of Sol, then when the mines arrived and he was on like 1/4 health, I (the one without a Gjallarhorn) went and dismantled them while my other two teammates finished off Skolas with a couple of Gjallarhorns and Blackhammers.
